"Ccaps" also known as "capabilities" are membership or purchase options that act as level restrictions.For example, your Level 1(or 2 or 3 or 4...) subscribers or buyers can access Capability 1 through the payment of such amount and / or Capabilities 2 through the payment of another amount.It is also possible to cumulate the capabilities so that your membership and / or purchase levels are unlimited.You will find the official explanations via the plugin in this section:s2Member → Scripting API → Custom Capabilities
